Chemical Evolution of the Exceptional Arctic Stratospheric Winter 2019/2020 Compared to Previous Arctic and Antarctic Winters
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Atmospheres, 2021-09-21)
The winter 2019/2020 showed the lowest ozone mixing ratios ever observed in the Arctic winter stratosphere. It was the coldest Arctic stratospheric winter on record and was characterized by an unusually strong and long‐lasting ... -
Large-Amplitude Quasi-10-Day Waves in the Middle Atmosphere During Final Warmings
; (Journal of Geophysical Research: Atmospheres, 2019)
Geopotential height measurements from the Aura Microwave Limb Sounder between 9- and 97-km altitudes during 2004–2018 are used to examine long-period (3–20 days) wave activity during the Northern Hemisphere winter and ... -
Near-Complete Local Reduction of Arctic Stratospheric Ozone by Severe Chemical Loss in Spring 2020
; ; Lehmann, R.; ; ; ; Davies, J.; ; Jepsen, N.; ; Lyall, N.; Rex, M. (Geophysical Research Letters, 2020)
In the Antarctic ozone hole, ozone mixing ratios have been decreasing to extremely low values of 0.01–0.1 ppm in nearly all spring seasons since the late 1980s, corresponding to 95–99% local chemical loss. In contrast, ... -
Stratospheric influence on ECMWF sub-seasonal forecast skill for energy-industry-relevant surface weather in European countries
; ; ; (Quarterly Journal of the Royal Meteorological Society, 2020)
Meteorologists in the energy industry increasingly draw upon the potential for enhanced sub-seasonal predictability of European surface weather following anomalous states of the winter stratospheric polar vortex (SPV). How ... -
Vortex-Wide Detection of Large Aspherical NAT Particles in the Arctic Winter 2011/12 Stratosphere
; ; ; Khosrawi, F.; (Geophysical Research Letters, 2019)
Micron-sized HNO3-containing particles in polar stratospheric clouds are known to denitrify the polar winter stratosphere and support chemical ozone loss. We show that populations of nitric acid trihydrate (NAT) particles ...
